Thanks Johnny - I'll save this for the next time - as I indicated, it 
seems to be working again but I have no idea why... I was not running it 
inside of Netbeans - I was actually copying the war file to a separate 
tomcat installation and running it there - but your suggestion makes 
sense and if it happens again, I'll give it a try...

thanks!
